[Zope] comparitive opperators

[Chris McDonough]

Read the DTML Reference (search for expressions or the "expr" tag).

It's at http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.html

Here's an example:

<dtml-call "REQUEST.set('var1',0)">
<dtml-call "REQUEST.set('var2',1)">
<dtml if "var1 != var2">
   <dtml-var var1> is not equal to <dtml-var var2>
</dtml-if>

Setting variables for use in DTML in the REQUEST namespace is a
convention.  You can compare almost any two objects this way, though
(such as the field result of a SQL method to the title_or_id of a Zope
object).

Note that writing <dmtl-call "REQUEST.set('var1',0)"> is equivalent to
<dtml-call expr="REQUEST.set('var1',0)">.  The former is shorthand for
the latter.
